And the integrated aluminum and soft elastomer Tuned Feel System in the back cavity improves sound and feel at impact. A soft, forged carbon steel body with a high density tungsten nickel sole .
The Titleist R&D team's advanced research group has been conducting extensive sound and vibration analysis aimed at reducing the harsh lower frequency vibration that causes poor feel in irons. This research led to combining several technologies and materials in the back cavity of the new AP irons resulting in a new Tuned Feel System to take feel to a new level. The new Tuned Feel System is a co-molded medallion of soft elastomer and aluminum plate.
All in all,You Can Feel the advanced performance,High quality, high technology design and construction featuring a forged steel body, tungsten nickel box and Tuned Feel System enhances performance and feel.
